While test driving monitored shift data and found TCM is commanding all gears with the correct gear ratios. Checked fluid level and condition and found fluid level is proper and fluid is clean. Back probed transmission connector and commanded shift solenoid one on and found the tcm is providing ground to the solenoid. Inspected fuse for shift solenoid and found the fuse is intact. While commanding the shift solenoid on and off there is no audible click. Will need to gain access to the shift solenoid for further diagnosis and inspection. Notified customer and they approved to removed transmission side cover for further inspection. Removed fuse panel, pcm, upper transmission mount and removed left side axle.
